Longmont Police Sgt. Bruce Pettitt said Vigil and the two juveniles agreed to purchase marijuana from the alleged victim but pistol whipped him and beat him instead. The victim was taken to a local hospital for treatment and was released.

Police were able to identify Vigil and took him into custody. The juveniles were rounded up a couple of hours later once they were identifed, Pettitt said.

It's been 20 years this month since three people -- a 9-year-old girl, her dad, and a man who worked for him -- disappeared. Westminster investigators believe the trio were murdered and their bodies hidden.
